During this week I shall be almost constantly engaged with a friend in some scientific labors which we are prosecuting together.
I am acquainted with no fact which would lead me to suppose that the project of the electro-magnetic telegraph is unpractical; on the contrary, I believe that science is now ripe for the application, and that there are no difficulties in the way but such as ingenuity and enterprise may obviate.

But what form of the apparatus, or what application of the power will prove best, can, I believe, be only determined by careful experiment.

I can say, however, that, so far as I am acquainted with the minutiae of your plan, I see no practical difficulty in the way of its application for comparatively short distances; but, if the length of the wire between the stations is great, I think that some other modification will be found necessary in order to develop a sufficient power at the farther end of the line.
I shall, however, be happy to converse freely with you on these points when we meet.

In the meantime I remain, with much respect Yours, etc., JOSEPH HENRY.
I consider this letter alone a sufficient answer to those who claim that Henry was the real inventor of the telegraph.

He makes no such claim himself.
In spite of the cares of various kinds which overwhelmed him during the whole of his eventful life, Morse always found time to stretch out a helping hand to others, or to do a courteous act.
